Great tools to look at your website speed

There are loads of good toolsets available online for testing and optimising the performance of our websites, but hats off to Gift Of Speed and in particular its terrific Page Speed Tools offering. These free tools will be of great interest to any of us who are interested in the technical performance of our websites, and include:

  • Base64 Encoder: Encode web files to a Base64 string to reduce the amount of HTTP requests that are being made by a web page.
  • Broken Link Checker: Check a web page for broken links, images, scripts, etc.. so you can replace/remove them from the page.
  • Caching Test: Check which files are cached on a website and by which method.
  • CSS Compressor: Automatically compress CSS scripts and files to a much smaller file size. Minimizing the file size improves page speed.
  • CSS Optimization Test: Test how well the CSS delivery of a web page is optimized, and learn how to improve it.
  • CSS Sprites Generator: Combine multiple images to one image file to reduce the number of HTTP requests.
  • HTTP Requests Checker: Check how many (and which type of) HTTP requests a web page makes. Reduce requests to improve page loading times.
  • Image Optimization Test: Test a website to find unoptimized images, and learn what you can do to optimize the images for a better page speed.
  • JavaScript Compressor: Compress JavaScript by improving and removing bad and unnecessary code. Supports file uploads as well.
  • JPEG Compressor: Compress JPEG images to the smallest possible size to reduce the file size and improve page speed.
  • Keep-Alive Checker: Test whether a website’s server has keep-alive enabled.
  • Line Breaks Remover: Remove line breaks and unnecessary whitespace to minify web files (ie. HTML), and reduce the file size.
  • PNG Compressor: Minify the file size of PNG images to speed up page loading times.
  • Gzip / Brotli Compression Test: Check if your website has gzip or Brotli compression enabled, and how well it compresses your web files.

In addition, there’s a very good general Page Speed Test.
